I came up with this a while back, which kind of gives you a ballpark figure comparing engine hp vs rwhp. Basically need at least 3 known variables. 1.A baseline

I came up with this a while back, which kind of gives you a ballpark figure comparing engine hp vs rwhp.

Basically need at least 3 known variables.
1.A baseline engine (assuming 332hp)
2.A baseline @ the wheels on a rolling dyno (stock)
3.A final number @ the wheels on a rolling dyno (with all bolt-on mods, etc.)

Quote:

Assuming 332hp @the crank & 275hp baseline @the wheels.

332 bhp x Y (whp gain)/275 whp= X (bhp gain)

Example 1:
for a 20 whp gain on the final dyno reading with all mods

332 bhp x 20whp/275 whp= 24.15 bhp gain
332 bhp + 24.15 bhp gain= 356.15 bhp @ crank

Example 2:
5 whp gain on the final dyno reading with all mods

332 bhp x 5whp/275 whp= 6.04 bhp gain
332 bhp + 6.04 bhp gain= 338.04 bhp @ crank
